Many Hands Make Light Work: Java EE Concurrency

The Java EE concurrency API is to compute-intensive tasks what multilane freeways are to traffic management.

For many years, computation tasks could be performed more and more quickly because of improvements in one aspect of the underlying processing power of processors: the chip speed. However, as the chip architectures started to approach the physical limits of what could be manufactured, chip designers turned to another technique to increase the computing power of their architectures: parallel processing. In terms of managing traffic on roads, this is rather like the realization that ...
